Summary

Participants will take part in both a passive and active emotion recognition task: (1) passively listening to semantically-neutral sentences with emotional prosody, and (2) actively listening and subsequently categorizing emotional sentences and sounds. Participants are seated and instructed to stare at a fixation cross while the stimulus is played. During this study, non-invasive physiological measurements of pupil dilation will be recorded from the participants. Using this paradigm we will be assessing the effect of frequency lowering on emotion recognition. The study takes the form of a partly three factorial design (passive task x frequency lowering x acclimatization). Participants also perform a two factor design (active task x frequency lowering). Each participant performs two passive tests (20 minutes long each) with frequency lowering on and off, and a four week acclimatization period in-between. Participants perform one active listening task after the acclimatization period with frequency lowering on and off.

Conditions

Interventions

DEVICE

Hearing Aid without frequency lowering enabled

Each participant will be fitted with frequency lowering disabled. Disabled means standard hearing loss compensation without lowering higher frequencies in lower frequency areas. The input frequency is mapped to the same frequency in output.

DEVICE

Hearing Aid with frequency lowering enabled

Each participant will be fitted with frequency lowering enabled. The principle of the frequency lowering algorithm is to lower high frequencies to a lower frequency region with the aim of ensuring high frequency audibility to improve auditory emotion recognition.
